Revision 2205 - (show annotations) (download)
Mon Jul 11 17:52:01 2011 UTC (7 years, 6 months ago) by iliev
Original Path: linuxsampler/trunk/configure.in
File size: 57660 byte(s)
* Introduced Signal Units and Signal Unit Racks, which hopefully will meet
  the demands of the new engines for flexible signal processing.
* sf2: Initial implementation of vibrato LFO, fixes in modulation EG and
  and volume EG (work in progress)

11 # The following is the libtool / shared library version. This doesn't have to
12 # do anything with the release version. It MUST conform to the following rules:
13 #
14 # 1. Start with version information of `0:0:0' for each libtool library.
15 # 2. Update the version information only immediately before a public release of
16 # your software. More frequent updates are unnecessary, and only guarantee
17 # that the current interface number gets larger faster.
18 # 3. If the library source code has changed at all since the last update, then
19 # increment revision (`c:r:a' becomes `c:r+1:a').
20 # 4. If any interfaces have been added, removed, or changed since the last update,
21 # increment current, and set revision to 0.
22 # 5. If any interfaces have been added since the last public release, then increment
23 # age.
24 # 6. If any interfaces have been removed since the last public release, then set age
25 # to 0.
